Maintenance
Checks before operation
If you plan to idle the unit for a long time, perform the
following:
(1) Operate the fan for about half a day to dry the
inside of the unit.
(2) Stop the air conditioner and disconnect power.
(3) The outdoor unit requires periodic maintenance
and cleaning. Do not attempt to do this yourself.
Contact your dealer or servicer.
Remove the batteries from the remote controller.
Check that the wiring is not broken off or disconnected.
Check that the air filter is installed.
Check if the air outlet or inlet is blocked after the
air conditioner has not been used for a long time.
Do not touch the metal parts of the unit when
removing the filter. Injuries can occur when
handling sharp metal edges.
Do not use water to clean inside the air conditioner.
Exposure to water can destroy the insulation,
leading to possible electric shock.
When cleaning the unit, first make sure that the
power and circuit breaker are turned off.
